The steps are quite simple:
1- Start multiMAN on the PS3 that will act as server (the one that has the ISO that we want to run).
2- On multiMAN go to Settings column and set "Remote Access Permissions" to
Full
3- On another PS3 use webMAN or multiMAN to connect to the PS3.
a) If you use webMAN:
- Go to /setup.ps3, put a check mark on Scan for LAN games/videos PS3NETSRV#1 (2 or 3...), enter the IP address of the PS3 acting as server, enter 38008 as port and save!!
- Use webMAN file browser to navigate to the folder containing the ISO in /net0 (or /net1, etc.) and mount it clicking on the 2nd column (size column).
b) If you use multiMAN:
- Go to Settings column, press X on Network Servers option, enable /net_host0 and enter the IP address of the PS3 acting as server, enter 38008 as port, enter a friendly name (press START on each prompt).
- Now you can go to mmOS (SELECT+START), navigate to the folder containing the ISO in /net_host0 and mount it double clicking on the file (press X twice).
IMPORTANT: multiMAN must be always running on the PS3 acting as server, unless you use webMAN MOD "full edition" (which has implemented its own PS3 NET Server).
Multi-part ISO or games in JB folders cannot be mounted with multiMAN's PS3 NET Server (neither with webMAN MOD's PS3 NET Server).
